Who will step up to challenge the Iron Men?

The Celtic Warrior & The Swiss Superman work together like a well-oiled machine in their title defense against Matt & Jeff Hardy: Courtesy of the award-winning WWE Network.

No shenanigans this time: Cesaro & Sheamus retained the Raw Tag Team Championship over The Hardy Boyz by winning a 30-Minute WWE Iron Man Tag Team Match (four falls to three). Now that “The Bar” has put Team Xtreme in their rearview, are there any red brand tandems with a claim to challenge them? And even if there are, do any of them stand a chance?
